Determining the Condition of the Clock Recovery PW on the
Distribution Unit
In order to generate the Clock PW packets, the TDM interface that will be the
clock source of the node should be in sync/up state.
³
To determine the status of the Clock Recovery PW:
1.
Go to Configuration>System>Clock>Master clock.
1. Source > (Rx Clock)
...
4. Port type > (ATM-155)
5. Port number[1 - 16] ... (1)
2.
Go to Monitoring>System>Active alarms.
3.
Make sure that the clocking interface is not in LOS condition.
4.
If it is in LOS condition, try using an alternative clock port for the system
clock (another E1 port, STM-1 port etc).
5.
If another clocking port unavailable, make sure that the clocking interface is
properly connected and that the clocking device connected to this port is
operational. Validate physical connections by replacing wires, ports etc.
6.
If the physical level is operating properly, go to
Monitoring>Applications>Multiservice over PSN>PW>Status.
7.
Ensure that the PW Operational status is Up and the local status is set to
Forwarding.

8.
If the PW Operational status is Down, continue investigating using the
PW/VCCV-BFD Failure procedure (RAT Entry #3).
9.
If the cause of the failure is still unknown, reboot the clock recovery unit.
